摘　　要：研究了不同预养护时间下硅酸盐水泥-铝酸盐水泥-硬石膏三元体系的干缩变形行为和失水情况。研究发现,单掺铝酸盐水泥或硬石膏时,随着掺量的增加,硬化水泥石的干缩变形增大;同时掺入铝酸盐水泥和硬石膏时,会彼此减弱体系干缩变形的能力,并通过微观性能试验对其进行了机理分析。The dry shrinkage and dehydration of ternary system of portland cement-alumina cement-gypsum under different pre-curing ages are studied. The research shows that the dry shrinkage of hardened cement stone will increase while increasing the mixing amount of either alumina cement or gypsum. While mixed with both alumina cement and gypsum, the ability of dry shrinkage will be decreased by each other. And the mechanism analysis on the ternary system is carried out by micro-performances experiment.
